DUPLEX LOCKING MECHANISM FOR SAFES OR VAULTS.

SPECIFICATION forming part of Letters Patent No. 691,942, dated January 28, 1902.

Application filed July 27, 1901.

'l'o all whom it may concern: Be it known that I, HENRY D. HIBBARD, a citizen of the United States, residingin Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Duplex Locking Mechanism for Safes 0r Vaults, of which the following is a specification.

This invention relates to lock mechanism particularly adapted for safes or vaults, the object of the invention being to provide an improved organization or system of lock mechanism comprising one or. more dual locks, and isin part an improvement upon the mechanism shown and described in my contemporaneously-pending application, filed No vember 2, 1900, Serial No. 35,197, and now eventuated in Patent No. 679,378, dated July 30, 1901.

Another object of the invention is to provide detachable lock mechanisms dependent for their detachability upon the setting of a part of one of said mechanisms in a predetermined manner.

A further object of the invention is to provide lock mechanism in which the time and combination locks are disposed in juxtaposition and connected together in an improved manner, one to control the other.

A further object of theinvention is to provide lock mechanism, including one or more time-locks, located in an improved manner in juxtaposition to and in front or rear of a combination-lock and connected therewith so as to control the same, and which time lock' or looks can be readily detached intact from the combination-lock to permit the use of such combination-lock independently of the time-lock.

In the drawings accompanying and forming part of this specification, Figure 1 is a rear view of a safe or vault door with one form of bolt mechanism and its operating means combined with apair of improved dual locks applied thereto. Fig. 2 is a top view of one of the dual-lock mechanisms. Fig. 3 is a longitudinal sectional view taken in line a a, Fig. 2. Fig. 4 is a top view of the timelock mechanism detached from the combina bferial No. 69,899. (No model.)

tion-lock mechanism. Fig. 5 is a top view of the combination-lock mechanism detached from the time-l0ck mechanism. Fig. 6 is a view of this improved lock mechanism detached from the door and the means controlled thereby, and Fig. 7 is a view of a part of the time-lock casing.

Similar characters of reference designate corresponding parts in the various figures of the drawings.

The door in the form shown is substantially similar to that illustrated in my contemporaneously-pending application hereinbefore referred to, and therefore only a general description thereof is deemed necessary herein. This door comprises a body having a rearwardly-extending flange, to which is secured a back plate 2, which preferably carries va rious parts of the bolt-actuating mechanism, and which plate will also carry in the present instance the lock mechanism.

The door-flange is provided with bolt-openings 3, located at intervals, each of which is shown of tapered form, obtained by inclining one side of each opening. Workingin these openings are bolts 4, pivotally secured at their inner ends to a rocking member or plate 5, having worm-teeth 6 on a part of its periphery. This rocking plate is mounted on a hub or projection preferably formed rigid with the back plate, and is in mesh with a worm 7 of a worm-shaft 8, mounted in suitable bearings carried by the plate between such plate and the door. This worm-shaft is provided with a beveled gear 9, in mesh with a similarlyformed gear 10, carried by a spindle 12, projecting through the door to the front thereof, and by means of which spindle on the rotation thereof the worm-shaft is rotated. To prevent the rotation of this worm-shaft except at the proper time, suitable controlling means is provided, shown in the form of clutch mechanism, and in the present instance the gear 9 is carried by or formed as a part of a loosely-mounted clutch member 9', rotatable on such shaft and in position to be engaged by a clutch member 13, splined to such shaft, which clutch member 13 is controlled by the lock mechanism hereinafter described.

In the preferred form thereof herein shown and described the lock system in the present instance comprises a pair of combinationlocks (designated in a general way by A) and two sets of time-locks, (each set designated in a general way by B,) each set comprising a pair of time-locks, one set for each combinationlock. this improved lock mechanism may in some instances comprise one time-lock for each combination-lock or in some instances one time-lock for a plurality of combination-locks, or the system may comprise one or more timelocks and one combination-lock. It is, however, preferable to provide apair of combination-locks, since should one of them become inoperative for any reason the other can be utilized to operate the bolt system, thereby to unlock the door without the necessity of forcing the same, and it is also preferable to provide in connection with each of the combination-locks a pair of time-locks, whereby should one of the time-locks become inoperative the other will be effective to permit the combination-lock to be manipulated. Further, by providing a pair of combinationlocks, one of such locks may be permitted to respond to its combination and yet not be effective to unlock the safe, thus demonstrating that the proper combination had been divulged, but that until the expiration of the time set for the time-lock to operate the safe or vault cannot be opened. a

In the form shown each of the lock mech anisms is connected with the clutch member 13, whereby at the proper time such clutch member can be shifted by the manipulation of either combination-lock into engagement with the clutch member 9, thereby to form connection between the worm-shaft and bevelgear 9 of such clutch member 9, so that upon the operation of the spindle the worm-shaft will be rotated to shift the bolt-s which move in a lateral and longitudinal or radial path and operate with a toggle action to draw the 7 door to its seat with considerable force.

Since in the present instance the organization of each lock mechanism is the same a description of one is deemed sufficient.

The combination-lock may be of any desired form and usually comprises a suitable casing 15, carrying a spur-gear 16, mounted on the dial-spindle, which gear meshes with asimilar gear 17, the spindle or arbor of which carries a series of disk'shaped tumblers 18, each having a notch 19. In mesh with this gear is a smaller gear 20, on the arbor of which is mounted alever or fence 2i, the hub thereof having teeth 22. This fence is so mounted that at certain periods the gear 20 will turn independently thereof, while at other periods friction will cause such fence to turn with the gear. Mounted in the lock-casingis the usualbolt or actuator 24, provided with gear-teeth 25, meshing with the teeth 22 of the fence. When the dial-spindle is operated, the tumblers will be rotated in the usual manner It is, however, to be understood that until the notches of all such tumblers register, whereupon the fence by means of the gear 20 will be shifted into position to have its end enter such notches, whereupon it will be rotated with such tumblers to shift the bolt or actuator 24.

The bolt of each combination-lock is shown recessed, each for the reception of the ends of levers 25 26, respectively, the opposite ends of which are connected with the splined clutch member 13 by suitable means, whereby the operation of either combination-lock will shift such splined clutch member into position to engage the loosely-mounted clutch member 9' in the manner hereinbefore set forth. In the present instance the ends of these levers 25 26 are pivoted to a floating member or hellcrank 27, to which is connected a clutchshifter.28, pivoted to the back plate, one end of which clutch-shifter is bifurcated in the usual manner for connection with the splined clutch member 13. On the operation of either bolt the bell-crank will be shifted, either the pivot a or b acting as the fulcrum thereof, and thereby move the clutch-shifter to throw the splined clutch member 13 into engagement with the loosely-mounted clutch member 9'.

In the present instance the combinationlock casing 15 is shown of somewhat greater depth than is necessary for the working parts of the lock. I

To nullify temporarily the control of the combination-lock over the bolt mechanism, and thereby prevent the manipulation thereof should the combination be secured by duress from one familiar with it, improved timelock mechanism is provided, which in the form shown comprises two sets of time-locks, one set for each combination-lock. A description of one time lock mechanism is deemed sufficient. Each set comprises two independent time-locks 3O 30, located in a casing 29 and connected, however, by a suitable member 31, carrying a pair of stops 32, in position to be engagedvby working faces 33 of such time-locks. Pivoted to this member 31 are a pair of levers 34, which are also pivoted to a bracket fixed to the lock-case, the opposite ends of which are pivotally secured to an actuator 35, having an elongated slot 36, into which projects a pin 37, carried by a lever 38, such elongated slot permitting the proper working of the parts. This lever 38 is fixed on a spindle 39, working in a suitable bearing 40 of the lock-case, said lever being maintained in its normal position and being returned thereto by a suitable spring 41,- shown connected with one end of the catch 42, hereinafter described, and with a fixed point. Fixed on this spindle, at the lower end thereof, in juxtaposition to the combination-lock, is a device (shown herein as a hook or catch 42) in the nature of a stop member, cooperating with a projection24, formed on the bolt 24 of the combination-lock shown in Fig. 5. When the member 31 is the combination-lock in the manner hereinbefore set forth. As hereinbefore stated, one time-lock might be used instead of two for each combination-lock.

In the present instance the bolt of one coinbination-lock is shown dogged by the catch of one set of time-locks, while the fence 21 of the other combination-lock is (logged by the catch 42 of the other set of time-locks. It will be obvious, however, that either both bolts or both fences may be dogged instead of a fence and abolt. By dogging the fence of one and the bolt of the other combinationlock, however, that look the bolt of which is dogged will respond to its combination without, however, permitting the boltwork to be shifted, and so indicate that the proper combination has been divulged, there being sufficient play between the gearing of the fence and the bolt to permit the fence to drop into its notches without, however, shifting the lock-bolt. This would demonstrate toa burglar that even with the proper combination the opening of the safe is not possible until the time set for the time-locks to operate has expired. When the fence instead of the bolt is dogged, the combination-lock will not respond to manipulation, since it is locked against any movement whatever and cannot therefore be moved to drop into the tumblernotches.

In the form shown each set of time-locks controlling its combination lock is located in juxtaposition to such combination-lock and in such position relatively thereto that its working parts are in a plane substantially parallel to the plane of the working parts of the combination -lock-that is to say, the combination-lock is in the rear or front of said time-locks, whereby considerably less door area is required to mount the lock mechanism, such time-locks being readily detachable from the combination-lock, whereby the latter can be used without the former whenever it is desired so to do and the time-locks readily located in position when it is desired to control the working thereof by this means.

When the combination-lock is used alone, its casing 15 will be closed by a suitable plate; but when used in connection with the timelocks the bottom 29' of the casing 29 of such time-lock will constitute the top of the combination-lock casing 15, the two casings being secured together in an improved manner. In the present instance part of the time-lock casing 29 projects into the combination-lock casing 15, such casings being secured together by a screw 50 at one end, Fig. 3, and by a pin-and-slot connection at other parts thereof, the organization being such that one cannot be detached from the other without shifting the time-lock casing relative to the combination-lock casing in a particular manner. The time-lock casing is provided with a flange 50, adapted to rest on the edge of the casing 15, and it is also provided with a pair of pins or projections 51, cooperating with a pair of recesses 52, one formed at each side of the casing 15, each such recess comprising apart 53, communicating with the upper edge of the casing, and a slot 54, extending lengthwise thereof, whereby the casings may be locked together in a manner which will be readily understood by inserting the casing 29 into casing 15 and then shifting the casing 29 lengthwise to carry its pins into the slots 54. This pin-and-slot connection it will be seen forms substantially a bayonetjoint connection. To-prevent the shifting of one casing relatively to the other to detach the same, a projection is formed on the under side of the timelock casing 29, Fig. 3, in position to register with the notches in the tumblers, whereupon when in register therewith the time-lock casing can be shifted to the left to permit the projection 60 to enter .the recesses in the tumblers, and thereby permit the separation of the casings. From this it will be seen that unless the tumblers have all of their notches in register and in register with the projection 60 the separation of the two casings cannot take place. I

By locating the time and combination locks in juxtaposition, but readily separable from each other, the combination-lock may be used independently of the time-lock when preferred, but the latter quickly and easily at tached when desired without any reorganization or reassemblage of mechanisms. Furthermore, this organization materially simplifies the parts and does away with the dogging-levers necessary when the combination and time locks are located relatively remote to each other. By looking the casings together it is not possible for any one when the safe is open to surreptitiously detach the timelock, and so discover the organization of or reset the combination-lock.

Bylocating one look mechanism in j uxtapositionto the other and when a pair of casings are used one within the other the locks can be more closely assembled, so that the distance such locks will project from the door into the interior of the safe is materially diminished.

By means of the present organization the lock mechanism will take up very much less area both in the plane of the door as well as interiorly of the safe.

The term detachable or detachably connected or equivalent expression as used herein and in the claims means that one look mechanism or one look mechanism and its casing can be separated or detached from the other without the necessity of dismantling or tampering with any part of the mechanism of either look. In other words, by simply removing the top casing containing the time-lock from the lower casing containing the combination-lock the mechanisms will be readily separated Without the necessity of first removing pivots, screws, or bolts, so that one mechanism can be readily detached from the other without interfering with pivotal connections of any part of the mechanisms of either lock. Consequently two mechanisms which are separable only after various screws,

pivots, or parts of one or both have been removed or disconnected are not readily detachable one from the other Within the meaning of the terms detachable or detachably connected as used in those claims where this is an essential feature.
